    The issue identified with PI System Connector 2.3.0.1 has been resolved, and PI System Connector 2.3.1.1 is now available with snapshot support for PI Points that have compression disabled/off.

    We are still on track for a follow up release in Q1 2021 that will expand upon the snapshot support introduced in 2.3.1.1 by adding configuration options and snapshot support for compressed PI Points.

    Hey Matthew, really? So the System Connector team now plans on supporting snapshots? If they do that, give it a more full featured history recovery GUI, and allow for choosing archive modes then maybe it could replace PItoPI. I was disappointed with several aspects of System Connector but I did see some benefits: One-way firewall rules, seamless PI tag attribute sync, and more resilient to network issues (since using SDK vs API tech). I'm happy they're considering supporting snapshots though, that's vital.

    I wouldn't get your hopes up. I received an update on this on January 4, 2019 from a connectors product specialist at OSI. He reached out to the product manager for System Connector and they have decided not to support snapshot data collection with PI System Connector. On hearing this news my org has decided to remove System Connector and go with PItoPI/APS instead. The PI System Connector seems like a half-baked solution right now. I've heard from OSI that it should not be seen as a PItoPI replacement (see here) but instead should be seen as a solution for migrating AF DB structure from one AF environment to another. However, as of now, System Connector doesn't support migrating Analyses or Notifications. I have to say that System Connector seemed to handle PI tag creation/updates a lot more seamlessly than APS but also there was much less control and customization. With time I'm sure System Connector will become a solid product but seems lacking as of now.

    I heard that this feature is in the works. Is there a tentative timeline for this? Like everyone else here, I agree that this is a very necessary feature.

    I'd like to add to this suggested improvement. I'm using PI System Connector and ran into a scenario where the archive modes are necessary. I have an OPC Alarm and Events interface pushing to a "source" PI Data Archive and System Connector/Relay sends to a "destination" PI Data Archive. There are events that occur at the exact same timestamp that are substituted by default at the destination. Having the archive modes (similar to the PI to PI interface) would be ideal:

    ARCNOREPLACE add unless event(s) exist at same time (PI 2.x)

    ARCAPPEND add event regardless of existing events.

    ARCREPLACE add event, replace if event at same time.

    ARCREPLACEX replace existing event (fail if no event at time)

    ARCDELETE remove existing event.

    ARCAPPENDX add event regardless of existing events, with no compression.
